Genetics is the study of genes, heredity, and genetic variation in living organisms. It is generally considered a field of biology, but it intersects frequently with many of the life sciences and is strongly linked with the study of information systems.
Many estimates suggest that the long-run normal level of the unemployment rate--the level that the unemployment rate would be expected to converge to in the next 5 to 6 years in the absence of shocks to the economy--is in a range between 4.5 and 6 percent.any estimates suggest that the long-run normal level of the unemployment rate--the level that the unemployment rate would be expected to converge to in the next 5 to 6 years in the absence of shocks to the economy--is in a range between 4.5 and 6 percent.
History of U.S. Unemployment. The U.S. government began tracking unemployment officially in the 1950s, but estimates of previous unemployment rates are not difficult to ascertain. The Great Depression of the early 1930s had an unemployment rate of 23.6 percent â the highest in modern times. The countryâs lowest rate â 1.2 percent â came in 1944 when millions of men were in uniform and the wartime (World War II) economy was in overdrive. The lowest post-war rate was 2.9 percent in 1953. Since 1948, the end of the postwar period, the United States has experienced 11 recessions. Over that span, the federal government has employed various methods to push back unemployment caused by these cyclical contractions of the economy.
